This is the electric insect fogger that uses the same technology employed by state and local governments to kill mosquitoes. Using a clear liquid insecticide that gives off a slightly sweet scent, this device creates a 10' cone of fog that treats a 5,000' sq. yard in less than ten minutes. It provides protection against mosquitoes that may carry dangerous insect-borne illnesses such as the Zika virus, and West Nile virus, as well as the discomfort of itchy welts. Treatment lasts six hours and the area can be safe for use after five minutes. Plugs into AC. Includes one 32 oz. bottle that treats 1/2 acre. 15" L x 11" W x 7" D. (4 lbs.) Not available for shipment to Canada.
